The present embodiment carries out calculating judgement on the basis of B and D.When A, which is less than B ultrasound, crosses 5%, the upper cross of the judgement of PC host computer 10
Beam 3 is bent outwardly.Gasket can be increased in the outside of upper beam pin shaft 1, or reduce gasket in the inside of upper beam pin shaft 1, directly
To A and B difference within 5%.
When A, which is greater than B ultrasound, crosses 5%, PC host computer 10 judges that upper beam 3 curves inwardly.It can be in the outside of upper beam pin shaft 1
Gasket is reduced, or increases gasket in the inside of upper beam pin shaft 1, until the difference of A and B is within 5%.
When C, which is less than D, is more than 5%, PC host computer 10 judges that lower beam 6 is bent outwardly.It can be in the outside of lower beam pin shaft 4
Increase gasket, or reduce gasket in the inside of lower beam pin shaft 4, until the difference of C and D is within 5%.
When C, which is greater than D, is more than 5%, PC host computer 10 judges that lower beam 6 curves inwardly.It can be in the outside of lower beam pin shaft 4
Gasket is reduced, or increases gasket in the inside of lower beam pin shaft 4, until the difference of C and D is within 5%.
In order to further improve the press fitting precision of Press Fit Device for Wheelset, the mean value of A and B can be also further calculated with C's and D
The difference of mean value.Wherein, when as A, the mean value difference of C and D is more than 5% compared with the mean value of B, PC host computer 10 judges lower and upper cross-member
Pulling force deviation is excessive.When mean value of the mean value of A and B less than C and D is more than 5%, can increase simultaneously two inside and outside upper beam pin shaft 1
The gasket of side, or the gasket inside and outside lower beam pin shaft 4 is reduced simultaneously.
When mean value of the mean value of A and B greater than C and D is more than 5%, the pad inside and outside upper beam pin shaft 1 can be reduced simultaneously
Piece, or increase the gasket inside and outside lower beam pin shaft 4 simultaneously.
So far, Press Fit Device for Wheelset adjustment finishes.

For example either synchronously or asynchronously to be executed in multiple components.
As shown in fig. 6, a kind of method of the monitoring adjustment extremely eccentric press fitting of Press Fit Device for Wheelset, including step S101 is extremely
S103。
In step s101: monitoring the stress inside and outside Press Fit Device for Wheelset lower and upper cross-member respectively.
Wherein, it may be selected to monitor in upper beam lateral stress outside lateral stress and upper beam in symmetric position, answer on the inside of lower beam
Power and the outer lateral stress of lower beam.
In step s 102: analysis is compared to monitoring data.
In step s 103: based on the analysis results, increasing or reduce the gasket inside and outside lower and upper cross-member pin shaft.
Fig. 7 schematically shows the analytical judgment flow chart of the method for Fig. 6.
As shown in Figure 7, wherein lateral stress is A in upper beam, and the outer lateral stress of upper beam is B, and lateral stress is C in lower beam,
The outer lateral stress of lower beam is D, reads A, B, C, the stress data of D is compared judgement to it by benchmark of B and D:
When the difference of A and B is more than 5%, judge that upper beam there are additional bending moment, needs to be adjusted.Whether judge A
Judge that upper beam is bent outwardly if it is not, then A and B difference are more than 5% greater than 0.95B, can increase in the outside of upper beam pin shaft
Shimming, or gasket is reduced in the inside of upper beam pin shaft；
If it is, continue to judge whether A is less than 1.05B, if it is not, then A and B difference are more than 5%, judge upper beam to
Interior bending reduces gasket in the outside of upper beam pin shaft or increases gasket in the inside of upper beam pin shaft；
If it is, A and B difference are not above 5%, upper beam does not need to adjust.
Similarly, C and D uses same judgment method, and when the difference of C and D is more than 5%, it is additional to judge that lower beam exists
Moment of flexure needs to be adjusted.Judge whether C is greater than 0.95D, if it is not, then C and D difference are more than 5%, judge lower beam to
Outside sweep can increase gasket in the outside of lower beam pin shaft, or reduce gasket in the inside of lower beam pin shaft；
If it is, continue to judge whether C is less than 1.05D, if it is not, then C and D difference are more than 5%, judge lower beam to
Interior bending can reduce gasket in the outside of lower beam pin shaft or increase gasket in the inside of lower beam pin shaft；
If it is, C and D difference are not above 5%, lower beam does not need to adjust.
In order to further improve the press fitting precision of Press Fit Device for Wheelset, the mean value of A and B can be also further calculated with C's and D
The difference of mean value.Wherein, when the mean value difference of C and D is more than 5% compared with the mean value of B as A, judge lower and upper cross-member pulling force deviation mistake
Greatly.
Wherein, judge whether the mean value of A and B is greater than the mean value of 0.95 times of C and D, if not, upper beam can be increased simultaneously
Gasket inside and outside pin shaft, or the gasket inside and outside lower beam pin shaft is reduced simultaneously；
If it is, continue to judge A and B mean value whether the mean value of the C and D less than 1.05 times, if not, can subtract simultaneously
Gasket inside and outside few upper beam pin shaft, or increase the gasket inside and outside lower beam pin shaft simultaneously；
If it is, the difference of the mean value of A and B and the mean value of C and D is not above 5%, lower and upper cross-member does not need to adjust.
